SEEDBOX FOR GRAIN-DRILLS.

Specification of Letters Patent.

Patented Jan. 2, 1906.

To all whom it may concern;

Be it known that I, CHARLES L. FowLE, a citizen of the United States, residing at the city of Dowa me, in the county of Cass and State of Michigan, have invented certain new and useful Improvements in SeedboXes for Grain-Drills, of which the following is a speci-.

fication.

This invention relates to improvements in seedboxes for grain-drills and the like.

It relates particularly to means for securing the cover both in the closed and in the open posltion.

The objects of the invention are to provide an improved seedboX for grain-drills in which the cover is secured automatically and retained either in the opened or the closed position and is easily operated.

Further objects relating to details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of my invention is fully illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is-a detail perspective view of a part of a grain-box embodying the features of my invention. Fig. 2 is a detail transverse sectional view taken on a line corres onding to line 2 2 of Fig. 1, the cover being sliown in the closed position. Fig. 8 is a detail sectional view'taken on line 3 3 of Fig. 2.

Fig. 4 is a sectional view of the rock-shaft and spring. Fig. 5 is an enlarged detail view of the end of the retaining or looking rod C. Fig. 6 is an enlarged detail view of a modification of the locking-rod C.

In the drawings all the sectional views are taken looking in the direction of the little arrows at the ends of the section-lines, and similar letters of reference refer to similar parts throughout the several views.

Referring to the lettered parts of the drawings, the seedboX A is of the usual construction and is provided with a cover A, which is hinged in the usual or any desired manner. Within the seedbox I secure the transverse bracket B, which is provided with a longitudinal slot 1;, having enlargements at each end. On the under side of the cover I secure a rook-shaft D by suitable clips, as d. The rock-shaft D is provided with a finger-piece or lever D. This is adapted to extend beyond the edge of the cover and project outside of the seedboX, so that it maybe conveniently grasped for operating when manipulating the cover. A spring d is secured to the rock-shaft D, adapted to rest against the cover to hold the rock-shaft normally in its initial position'under spring tension.

Pivotally secured to the inner end of the rock-shaft D is a rod C, which is provided with a laterally-projecting tapered hook C at the end. The hook portion C is adapted to enga e the slot 5 in the bracket B. The slot 1) is slightly enlarged at I). These openings are of suflicient size to admit the hook portion C of the rod C, while the slot 1) is only large enough to permit the smaller tip portion of the hook to slide therein, so that when it is desired to open or close the cover the hook C must be partially withdrawn. The spring d returns the rock-shaft to its initial position and forces the hook C into engagement with one of the openings b as soon as the end of the slot is reached, thus locking the cover in either the open or in the closed position. I provide an additional means for holding the cover in its closed position'by providing a catch or hooked arm D (see Figs. 1, 2, and 3) on the rock-shaft D, adapted to snap onto andengage the bracket B when the cover is closed. This catch D is held yieldingly in engagement with the bracket B by the spring d on the rock-shaft D.

In the modified construction shown in Fig. 6 the stop 0 on the end of the hook C is omitted. The structure shown in the main figures is, however, preferred, as it provides a better stop.

My improved grain-box is simple and economical to construct and easy and durable to use. I have illustrated and described the same in the form preferred by me on account of the simplicity and economy in construction and durability in use. I am aware, however, that it is capable of considerable structural variation without departing from my invention. It will be seen that a single latch or locking means is provided with stops to adjust the cover either in the opened or closed position. This will also be seen to be of advantage with covers in other relations.

cured to the end of said rock-shaft, having a laterally-projecting portion. 0 adapted to engage said slot 1) and slide therein when partially withdrawn; and a catch 1 on said rock-shaft adapted to engage said bracket B when the cover is closed, whereby said cover is adjustably retained in either its open or closed position, as specified.
